The Japanese spacecraft Hayabusa 2 is now in orbit around near-Earth asteroid 162173 Ryugu, an asteroid about 1 km across that was discovered in 1999. It went into orbit on June 27, and it released on September 21 two rovers. Both of them have successfully landed on the asteroid. A third one is to land on October 3, and a fourth one to land next year.

The spacecraft itself is to land on the asteroid in late October. It will then shoot a small bullet at the asteroid and pick up the dust with a funnel-shaped collector. It will then shoot an explosive shell at the asteroid, move to the other side, detonate the shell, and then return to pick up bits of asteroid that were presumably below its surface.

Late next year, it will depart from the asteroid, and in 2020, some capsules from the spacecraft should return to the Earth with dust samples in them. The spacecraft will likely continue onward to explore other asteroids.


Late this year, the American spacecraft OSIRIS-REx should join Hayabusa 2 in visiting an asteroid. It will arrive at asteroid 101955 Bennu, collect a sample, and then send it to the Earth.

What a waste. To think that with the same money they could do something constructive, like attack Laos or build a wall around their country... no, instead they go ahead and make Americans look like insipid morons...

OMG. They nudge it, it hits another then another and the next thing you know an asteroid hits Earth an wipes us out.

Jape does not need a wall, surrounded by a lot of water. And if want to see a nationalist ethnic culture, try Japan.

MASCOT landing on Ryugu a success | The Planetary Society -- has some pictures from Hayabusa2 of MASCOT on its way down.

Hayabusa2's shadow is also visible, and the increased brightness around it is an  Opposition surge. It's what makes the full Moon so bright, and it has been seen in many other airless Solar-System objects. It is attributed to a combination of shadow hiding and coherent backscatter.


Also note that the asteroid is very dark, and that the bright spots that one sees are parts that are not as dark. It's like the Moon, with its albedo of about 0.12. The darkest asteroids go down to 0.06. The planets: Mercury 0.11, Venus 0.65, Earth 0.37, Mars 0.15, Jupiter 0.52, Saturn 0.47, Uranus 0.51, Neptune 0.41, Pluto 0.5 - 0.7

Two ways to look at this:

Pessimism...

Optimism... They nudge it. It hits another then another and the next thing you know an asteroid that would have hit Earth and wiped us out is nudged out of that path so that it misses us.

Japan is already surrounded by water... lots of water. Why waste money on a wall when they have literally noone on their border.
Why is Japan's success in space something that makes America look like morons?

I'm not following you people... science is good, unless someone else does it.

I'm unsure why your second point is relevant at all to a discussion about this particular topic. It does, however, make sense as a bullet-point on an agenda. Can we not have non-political discussions here?

Japan can't attack anyone, by NATO decree.

NATO is the North Atlantic Treaty Organization. Their remit does not include Japan, which is nowhere near the North Atlantic. NATO keeps the peace in Europe, by establishing a mutual defence treaty amongst member states. Japan has never been, nor is ever likely to become, a NATO member state.

And NATO doesn't decree non-violence - quite the reverse, NATO establishes an obligation for all member states to attack any non-member state that attacks any member state.

Japan can't attack anyone, due to the provision of Article 9 of the Japanese constitution, variously attributed to Allied Supreme Commander Douglas MacArthur, and Prime Minister Kijūrō Shidehara, and implemented by the Diet on November 3, 1946.

And what is it that put America in the forefront of the nuclear nations? And what is it that will make it possible to spend twenty billion dollars of your money to put some clown on the moon? Well, it was good old American know-how, that's what, as provided by good old Americans, like Dr. Wernher von Braun.

"Don't say that he's hypocritical,
Say rather that he's 'apolitical'.
Once the rockets are up,
Who cares where they come down?
That's not my department,
Says Wernher von Braun"


Jeez you people need to learn some history and popular culture. This stuff is not even particularly old, and it's from your own damn nation.

Those who forget satire are doomed to blunder into it again.

LOL You said "you people". Awesome.

Science is science. Despite all of the political BS between Russia and the US, we continue to work together on the space program. Go figure.

To much fraud in money science like genetics and bioscience two faces of eve for it to be a-anything. Oh I like the centers that store methods and data they give a nice patina to the idea that scientists are open and honest until one realizes that almost no one ever goes to them to verify whether this or that procedure is actually done according to Hoyle, or Bayes or Fisher or six sigma criteria.

He's my favorite. Bomb north of the Yalu Arthur. Whatta way to get clearance for his "Old Soldiers never die" speech to Congress. Always the one to find a way to get his medals burnished

Still, his years in Japan are probably the most important years spent by any American in the twentieth century

So if it's a bullet or a bomb it's gotta be for war, right? Damn cleaver, those Japanese.
